Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for knitting a stitch in a flat knitting machine having a front needle bed and a rear needle bed.

[0002]

2. Description of the Related Art When knitting a garment such as a sweater by a flat knitting machine in which a plurality of knitting needles are arranged in parallel on each of the front and rear needle beds so as to be able to advance and retreat, when a knitting cloth such as a sweater is knitted on a predetermined course according to the shape of the body. An increase in the number (that is, an increase in the number of eyes) is performed.

[0003] As one of such additional knitting methods, there is a technique described in Japanese Patent Publication No. 6-84583. According to this conventional technique, an additional portion is formed before knitting a course following a course to be increased. That is, in the prior art, an additional portion to be knitted in a loop of the next course is formed in a course to increase the number of stitches.

[0004]

However, in such a conventional additional knitting technique, a wool loop for increasing the number of meshes is simply divided into two, so that a knitting yarn connected to both divided loops is formed. As a result, the knitted fabric becomes unstable and dirty.

[0005] Therefore, when knitting an additional knitted fabric in a flat knitting machine, the knitted fabric has a well-balanced face.
It is important to have a beautiful face.

[0006]

In the knitting method of the present invention, a course to be stitched is knitted by a plurality of knitting needles of a first needle bed, and a wale to be stitched in the first needle bed is provided. A first step of forming an additional loop with a second knitting needle of a second needle bed positioned adjacent to the first knitting needle corresponding to the first knitting needle; A second step of transferring each loop locked by the knitting needle located on the increasing side from the first knitting needle on the first needle bed to each of the second and subsequent knitting needles toward the stitch increasing side; A third step of mutually intersecting the locked original loop and the additional loop locked by the second knitting needle.

[0007] In the first step, each loop of the course for which the number of stitches is to be increased and the number of the loops are knitted at the time of knitting of the loop by the predetermined knitting needles of the first needle bed and the second knitting needles of the second needle bed. Each loop is formed as a normal loop and an empty needle knit loop (addition loop).

[0008] The original loop in the normal loop and the looped loop of the empty needle knit are such that each loop located on the side of the first needle bed on the stitch increasing side with respect to the first knitting needle is the first loop in the first needle bed. After the transfer from the knitting needles to the second and subsequent knitting needles toward the stitch increasing side, they are interlaced with each other. For this reason, the original loop and the additional loop are constrained to each other and to the loop of the previous course, and as a result, the knitted fabric has a well-balanced face and a beautiful face.

In the second step, the loops locked to the knitting needles from the first knitting needle to one end of the stitch are transferred to the knitting needles of the second needle bed which are transferably opposed to those knitting needles. And transferring the transferred loops again to the second and subsequent knitting needles located on the side of the first knitting needle on the side of the first knitting needle on the first needle bed, which are locked to the first knitting needles. The second loop is transferred to the knitting needle located on the side of the second knitting needle which passes through the original loop, and the second loop knitted by the second knitting needle is transferred to the first knitting needle. The additional loop transferred to the knitting needle is the second
Transfer to the knitting needle located adjacent to the stitch increasing side of the knitting needle that has locked the original loop in the needle bed, and transfer the original loop on the second needle bed to the first knitting needle. The method may include transferring an additional loop on the floor to a knitting needle located on the first needle bed adjacent to the first knitting needle on the first knitting side.

[0010] The third step is to transfer an additional loop to a first knitting needle and to remove another loop excluding an original loop transferred from the first knitting needle to a first needle bed in a first needle bed.
Transfer to the knitting needle located next to the knitting needle on the first needle bed, and the knitting needle located on the knitting needle adjacent to the knitting needle holding the original loop in the second needle bed. Transferring, transferring the original loop on the second needle bed to the first knitting needle, and positioning the additional loop on the second needle bed adjacent to the first knitting needle on the first needle bed on the side of the first knitting needle. Transferring to a knitting needle may be included. By doing so, the original loop and the additional loop are reliably restrained to each other and to the loop of the previous course, so that the balance of the knitted fabric surface is further improved, and the mesh surface becomes more beautiful. Become.

[0011] In the first step, the yarn feeder for the course to be increased in the number of stitches is moved in the knitting direction to a position beyond the first or second knitting needle before the first or second knitting needle advances. And then advance the first or second knitting needle,
The yarn feeder is moved in a direction opposite to the knitting direction to a position beyond the first or second knitting needle, and then the first or second knitting needle is retracted to move the knitting yarn to the first or second knitting needle. Locking and moving the yarn feeder in the knitting direction can be included. By doing so, the original loop or the additional loop is twisted, so that the original loop or the additional loop in the knitted fabric becomes smaller.

[0012]

1 to 8 are views for explaining an embodiment of a method for knitting one extra stitch. The knitting is knitted using a flat knitting machine having front and rear needle beds in which a plurality of knitting needles are arranged in parallel so as to be able to advance and retreat.

In these figures, some of the knitting needles used for knitting the front needle bed are denoted by reference numerals N108, N109, N110, N111, N.
Part of the knitting needles used for knitting the rear needle bed is denoted by reference numerals N208, N209, N210, N211 and N212. The original loop and the additional loop are denoted by reference numerals R110 and R210, respectively. Furthermore, in (B) of those figures, the direction of transfer and the direction of racking are indicated by arrows without reference signs and arrows with reference signs R in (B) of those figures, respectively. The asterisk points indicate the knitting points and the points to be added (points to increase the number of eyes), respectively.

In the following description, racking is performed by relatively moving the front and rear needle beds in the left-right direction, and loop transfer is performed by moving a predetermined knitting needle of the front and rear needle beds. In addition, the main knitting may be performed by any of the knitting needles of the front needle bed and the rear needle bed,
In the following description, the main knitting is performed by the knitting needles of the front needle bed.

In the present invention, in the initial state prior to knitting, the front and rear needle beds are set so that their knitting needles are shifted in the left-right direction (for example, a half pitch). In the following description, the fact that the knitting needles of the front and rear needle beds face each other does not mean that both knitting needles are completely facing each other, but that the knitting needles can be transferred slightly shifted in the left and right direction. Say.

At the time of knitting, first, as shown in FIGS. 1A and 1B, a course C1 to be increased in stitches is knitted by a plurality of continuous knitting needles of the front needle bed, and an additional loop R210 is formed. It is formed by the second knitting needle N210 of the rear needle bed located adjacent to the first knitting needle N110 located on the wale where the number of stitches in the front needle bed is to be increased.

In this step, while the yarn feeder 10 is moved in the left-right direction to supply the knitting yarn 12 to a predetermined knitting needle, a predetermined number of the knitting needles of the front needle bed and the second knitting needle N210 of the rear needle bed advance and retreat. This is performed by causing Thus, Course C
One loop is formed by a plurality of continuous knitting needles on the front needle bed, and the additional loop R210 is formed by the second knitting needle N210 on the rear needle bed.

Next, as shown in FIGS. 2 (A) and 2 (B), the second knitting needle N210 which locks the additional loop R210.
The needle bed is racked so as to face the knitting needle N109 located on the side of the front needle bed on the side opposite to the first stitch needle N110. In the illustrated example, this step is performed by racking the rear needle bed in the direction of increasing the stitches (rightward in the figure), but is not limited to this. The needle beds may be moved in a specific manner, and only the front needle bed may be racked, or the front and rear needle beds may be racked simultaneously. The same applies to racking in the following steps.

In the above process, the tension caused by the racking of the needle bed acts on the loop R210. However, at this time, since each loop of the course C1 is not restrained, the additional loop R210 draws the knitting yarn of the course C1 by the tension acting on the loop to increase the length of the loop, thereby increasing the length of the loop of the course C1. The tension is averaged. Therefore, there is no possibility that the tension of the loop R210 becomes excessively large due to the racking of the needle bed.

Then, as shown in FIGS. 3A and 3B, the knitting needles N110, N111... From the first knitting needle on the first needle bed to one end of the knitted fabric on the stitch increasing side are locked. Loops R110, R111 ... are those knitting needles N110, N111.
... knitting needles N211 and N212 on the rear needle bed which are transferred so as to face
Transferred to ...

Next, as shown in FIGS. 4 (A) and 4 (B), the second knitting needle N210, which locks the additional loop R210 in the rear needle bed, is opposed to the front kuri and the first knitting needle N210. As a result, the rear needle bed is racked by one pitch in the eye increasing direction (leftward in the figure).

Next, as shown in FIGS. 5 (A) and 5 (B), the second knitting needle N210 of the rear needle bed to the first knitting needle N110 of the front needle bed are locked by the additional loop R210. , And locks each loop R111 of the rear needle bed except for the original loop R110 transferred from the first knitting needle N110 of the front needle bed to the knitting needle N211 of the rear needle bed in the previous step. Are transferred to the knitting needles N112 of the first needle bed which are transferably opposed to the existing knitting needles N212. As a result, the original loop R1
Each of the loops R111 on the stitch increasing side from 10 is moved to the knitting needles N112, which are located adjacent to the stitch increasing side of the original knitting needles N111, respectively.

Next, as shown in FIGS. 6 (A) and 6 (B), the additional loop R210 transferred to the front needle bed is the first loop of the front needle bed.
From the knitting needle N110 to the knitting needle N210 on the rear needle bed. As a result, the original loop R110 and the additional loop R210 are locked by the adjacent knitting needles N211 and N212 on the rear needle bed.

Next, as shown in FIGS. 7 (A) and 7 (B), the additional loop R210 transferred to the front needle bed is the first loop of the front needle bed.
From the knitting needle N110 to the knitting needle N212 on the rear needle bed. As a result, the additional loop R210 is moved to the knitting needle N212 located on the knitting needle N212, which is adjacent to the knitting needle N211 holding the original loop R210, so that the original loop N110 and the additional loop N210 are respectively adjacent to the rear needle bed. Two knitting needles N2 that fit
Locked to 11 and N212.

Next, as shown in FIGS. 8 (A), 8 (B) and 8 (C), the knitting needle N211 which locks the loops R110 and R210 of the rear needle bed and the knitting needle N211 is located adjacent to the stitch increasing side. After the rear needle bed is racked by one pitch in the eye increasing direction so that the knitting needles N212 face the first knitting needle N110 of the front needle bed and the knitting needle N111 located adjacent to the first stitch increasing side, respectively, the second stitching is performed. The original loop R110 and the additional loop R210 on the needle bed are transferred to the first knitting needle N110 of the front needle bed and the knitting needle N111 located adjacent to the first knitting needle N110 on the side of the first knitting needle. Thereby, all the loops are locked to the knitting needles of the front needle bed.

As a result of the above, one stitch is increased,
The additional knitting ends. Thereafter, after the rear needle bed is returned to the original position, knitting of the subsequent course is performed.

One embodiment of the knitted fabric is shown in FIG. As is clear from FIG. 9, the original loop R110 and the additional loop r210 are locked to each other to be surely restrained from each other, and the loop R010 of the wale W0 to be increased in the course C0 before the course C1. It is locked and securely restrained by the loop R010. For this reason, compared with the conventional knitting technique, not only the original loop R110 and the additional loop R210 are small, but also the eyelash of the knitted fabric is well balanced,
The eyes are beautiful.

When a plurality of stitches are to be simultaneously increased, the above-described steps may be performed in parallel with the knitting needles N110 and N111 for knitting needles other than the knitting needles N10 and N11. Further, in the step shown in FIG. 1, the loop R110 or the additional loop R210 of the wale for increasing the number of stitches may be a twist stitch. An example of forming such a twist stitch will be described with reference to FIG.

As shown in FIG. 10A, the twist stitch 2
0 is formed by the knitting needle W3 (first knitting needle N110) of the front needle bed, the knitting yarn 12 from the yarn feeder 10 is connected to the knitting needle W3.
The knitting needles W1 and W2, which are further rearward in the knitting direction, hold down the knitting needles, and the respective knitting needles are retracted, and the yarn feeder 10 is moving in the knitting direction indicated by the arrow 21a.

In the above state, as shown in FIG. 10B, when the yarn feeder 10 is moved forward of the position of the knitting needle W3 forming the loop R110 in the knitting direction, the knitting needle W3 is moved.
Is advanced in the direction shown by the arrow 24a, and the knitting needle W3
Is located above the yarn 12 from the yarn feeder 10.

Next, as shown in FIG. 10 (C), the yarn feeder 10 is retracted in the direction shown by the arrow 21b beyond the position of the knitting needle W3. Thereby, the yarn feeder 10 is moved to the knitting needle W3.
In contrast, the yarn 12 is moved from the front to the rear in the knitting direction, so that the yarn 12 passes through the hook at the tip of the knitting needle W3 from the front side to the rear side in the knitting direction, and is wound around the knitting needle W3 substantially half a turn.

Next, as shown in FIG. 10D, the knitting needle W3 is retracted in the direction shown by the arrow 22b. As a result, the yarn 12 is locked by the knitting needle W3 and pulled down while passing through the hook at the tip of the knitting needle W3 from the front side in the knitting direction to the rear side, so that a loop of the yarn 12 is formed.

Next, as shown in FIG. 10 (E), the yarn feeder 10 is advanced again in the direction shown by the arrow 21a beyond the position of the knitting needle W3. Thereby, the twist stitch 20 by the thread 12 is formed on the knitting needle W3.

Thereafter, as shown in FIG. 10 (F), while the yarn feeder 10 is advanced, a stitch is formed by the yarn 12 with the other knitting needles W4... In front of the knitting needle W3. The additional loop R210 can be formed in the same manner as described above.

When the original loop R110 and the additional loop R210 are torsion stitches, and when the torsion stitch 20
Are continuously formed in the knitting section, the steps shown in FIGS. 10A to 10E may be repeated for each knitting needle.

FIG. 11A is an enlarged view showing a part of the knitted fabric knitted to the course C1 with the original loop R110 and the additional loop R210 as torsion stitches 20, 20, and FIG.
Shows an embodiment of a knitted fabric further knitted up to course C2. In these knitted fabrics, the original loop R110 and the additional loop R210 are twisted once as shown in the dotted circles 26, 26.

FIG. 12 shows an embodiment of a so-called carriageless type flat knitting machine 30 having no cam carriage for reciprocating a plurality of knitting needles.

The carriageless flat knitting machine 30 includes two needle beds 32 arranged in a reverse V-shape, and a plurality of knitting needles 34 arranged in parallel with each other so as to be reciprocally movable. And a plurality of yarn feeders 10a and 10b each having one or more yarn introduction holes.

The front knitting needles 34 and the rear knitting needles 34 are assumed to meet each other slightly in the left-right direction, and intersect each other at the leading end when advanced. Each knitting needle 34 is reciprocated in a predetermined pattern in synchronization with the movement of the corresponding yarn feeder 10a or 10b by an actuator, preferably a linear motor, in a pattern based on a predetermined knitting plan.

The reciprocating movement pattern of each knitting needle 34 can be represented as a diagram in which the vertical axis indicates the amount of movement of the needle with the position of the tooth gap being zero, and the horizontal axis indicates the amount of movement or time of the yarn feeder. Such patterns are called wave patterns, knit patterns, operation patterns, needle movement patterns, and the like. Hereinafter, such a pattern is referred to as an “operation pattern”.

Different types of knitting yarns 12a and 12b are inserted into the corresponding yarn feeders 10a and 10b. The yarn feeders 10a and 10b each have a corresponding knitting yarn 12a.
And 12b are supplied to the intersection of the front and rear knitting needles 34 from above by the yarn supply device 36.
4 is reciprocated above the intersection. Yarn feeder 10a, 1
The movement of 0b is set based on a predetermined knitting plan.

Each of the yarn supply devices 36 has a common rail 38 mounted on the frame of the flat knitting machine so as to extend in the horizontal direction.
Are supported so as to be able to reciprocate in the longitudinal direction of the rail. Each drive mechanism for individually moving the yarn supply device 36 includes:
The rail 38 includes a pair of pulleys 40 rotatably attached to portions spaced apart in the longitudinal direction of the rail 38, and an endless belt 42 stretched over both pulleys.

Each of the yarn supply devices 36 includes a traveling body 46 supported on a rail 38 by a plurality of rollers 44 so as to be able to reciprocate in the longitudinal direction of the rail, a stay 48 extending from the traveling body 46, and an endless traveling body 46. And a connecting body 50 connected to the belt 42. The rail 38 has a guide groove for receiving a part of the roller 44.

The yarn supply ports 10a and 10b are attached to the ends of the stays 48 of the corresponding yarn supply device 36.
The corresponding endless belts 42 are reciprocated in accordance with the forward and reverse rotations of the corresponding rotation sources (not shown), so that the yarn supply devices 36 are individually reciprocated based on a predetermined knitting plan.

In the example shown in FIG.
6 only, when the flat knitting machine has three or more yarn feeders, a plurality of pairs of yarn supply devices 36 are arranged on the rail 38, or as shown in FIG.
